Cardiac prostaglandin release was studied in closed-chest dogs during acute coronary occlusion. Aortic and coronary sinus blood was obtained before, and at intervals after, balloon occlusion of the left anterior descending artery in seven dogs. Sampl

We recently reported that arterial baroreflex control of renal nerve traffic is impaired in renal hypertensive rabbits. The purpose of this study was to determine if vagal cardiopulmonary baroreflex control of renal nerve traffic is also impaired. Ex

SUMMARY The purpose of this study was to determine the relative influence of arterial baroreceptors and of cardiac receptors with vagal afferents on efferent cardiac sympathetic nerve activity during coronary artery occlusion. Changes in heart rate (

Experiments were done to characterize the vascular responses to stimulation of aortic and carotid chemoreceptors and to identify the efferent components of the sympathetic system which are activated in different vascular beds. The chemoreceptors were

Aortic preparations of 70 rabbits including the vasa vasorum were perfused in vitro by oxygenated saline under a pressure of 100 mm Hg. The main branches of the aorta were ligated and the perfusate, which irrigates the aortic lumen, but not the vasa

In dogs with denervated hearts intravenous infusions of epinephrine (1.0 to 3.0 µg/kg/min) caused marked acceleration of the heart rate and a significant reduction of intraventricular conduction time. Equal doses infused into the descending thoracic

In 97 dogs left atrial pressure was elevated to various levels up to 50 mm. Hg by partial constriction of the aorta. The effect of these pressures for from 30 min. to 3 hours on the accumulation of lung edema was then studied. Edema was estimated by

This study tests the possibility that pressoreceptors of the sinoaortic type may be located in thoracic vessels and innervated by thoracic afferent nerves. Heart rate and arterial pressure were recorded in anesthetized dogs with neural pathways intac

The hemodynamic effects of hyperbaric oxygenation were investigated in anesthetized dogs with acute myocardial embolism and infarction produced by injecting plastic spheres 325 micra in diameter. In 50 "control" animals with acute myocardial infarcti
